I'm going to be bold and say EZPZ - no greens, no guessing! Tuco - what is Go?

Completed the numerical journey.

Go is a beautiful board game, played a lot in asia (Japan, Korea, China). been there, played it.

Good morning. Start.

Mr Ooijer is correct. It is the world's oldest board game. Some say the opposite color circles in the Yin Yang symbol are Go stones. check out www.usgo.org

Done. Easy.

Difficulty score 15. No green.

Actually, I believe Mr. Ooijer is being extremely modest when he says he has played Go.

hmmm... that game reminds me a little bit of a grown up version of a kid's game I used to play called othello.

oh yeah... start

done

I'll check it out - I've heard of Othello but never played it.

drwho: way cool solution for the 9. I think the is a y-wing or some such solution for an 8 somewhere in the middle of the board (also a very difficult solution). I was just saying that anyone who could logically complete the puzzle was a way better person than I am.

drwho: My last thoughts on the expert from Friday. Your convoluted (and correct) solution for the 9 @R6C1 gave 4 more numbers but the final solution needed a y-wing at R5C9, R6C7, & R8C7. this eliminated the 6 as a candidate in R8C9, causing it to be a 9 and solving the puzzle. These 2 advaced techniques were the only way to logically solve Fridays expert without guessing (or making a lucky mistake).

othello is to go as checkers is to chess

Yes Dr. Who Mr. Ooijer is being extremely modest. President of the Dutch Go Association ?!! Wow!
